how can I get write event?

Question

Hi. I'm using nRF52832, SDK13, S132v4.0.2. 
 I'm making peripheral device using nRF52832.
And I can see it gets BLE_GATTS_EVT_WRITE event as below when central sends WRITE event. 
 static void on_ble_evt(ble_evt_t * p_ble_evt)
{
......
switch (p_ble_evt->header.evt_id)
{
......
case BLE_GATTS_EVT_WRITE:
{
}
}
} 
 How can I get event When central sends "write no need response"?
As I tested I can't get the event using "BLE_GATTS_EVT_WRITE". 
 I hope your reply.

Hi Roger, 
 You should have BLE_GATTS_EVT_WRITE when the central do a write command (write without response). As you can find in the paremeter for the event inside ble_gatts_evt_write_t we have an .op , meaning the type of operation.
And in BLE_GATTS_OPS list you can find write request and write command there. 
 We need to look at how you define your characteristic, if you allow write command or not ? When you do write command do you see the actual value was updated ?
